19 Aug 2025 — In the Linux kernel, the following vulnerability has been resolved: spi: cs42l43: Property entry should be a null-terminated array The software node does not specify a count of property entries, so the array must be null-terminated. When unterminated, this can lead to a fault in the downstream cs35l56 amplifier driver, because the node parse walks off the end of the array into unknown memory. • https://git.kernel.org/stable/c/0ca645ab5b1528666f6662a0e620140355b5aea3 •

19 Aug 2025 — In the Linux kernel, the following vulnerability has been resolved: sunrpc: fix client side handling of tls alerts A security exploit was discovered in NFS over TLS in tls_alert_recv due to its assumption that there is valid data in the msghdr's iterator's kvec. Instead, this patch proposes the rework how control messages are setup and used by sock_recvmsg(). If no control message structure is setup, kTLS layer will read and process TLS data record types.

This leads to a 4-byte out-of-bounds stack write in the fp[] array, which only has room for 16 elements (0–15). Fix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1. • https://git.kernel.org/stable/c/f62af20bed2d9e824f51cfc97ff01bc261f40e58 •

https://notcve.org/view.php?id=CVE-2025-38565
19 Aug 2025 — In the Linux kernel, the following vulnerability has been resolved: perf/core: Exit early on perf_mmap() fail When perf_mmap() fails to allocate a buffer, it still invokes the event_mapped() callback of the related event. On X86 this might increase the perf_rdpmc_allowed reference counter. But nothing undoes this as perf_mmap_close() is never called in this case, which causes another reference count leak. Return early on failure to prevent that. • https://git.kernel.org/stable/c/1e0fb9ec679c9273a641f1d6f3d25ea47baef2bb •

19 Aug 2025 — In the Linux kernel, the following vulnerability has been resolved: perf/core: Prevent VMA split of buffer mappings The perf mmap code is careful about mmap()'ing the user page with the ringbuffer and additionally the auxiliary buffer, when the event supports it. Once the first mapping is established, subsequent mapping have to use the same offset and the same size in both cases. The reference counting for the ringbuffer and the auxiliary buffer depends on this being correct.
